Review on Ruaeoda 2 Pack SSD Mounting Bracket Adapter - 2.5" to 3.5", HDD SSD Tray Holder, Metal Mounting Bracket Adapter for PC SSD, Hard Disk Drive Bays by Predrag Holman

Danger! The edges are very sharp. Sharp enough to cut your fingers when inserting and tightening the screws, and also when inserting into the hard drive bay. I had to file every edge of each of these hard drive trays. Luckily no stitches were needed. Not impressed. Quality control should have recognized this problem.
